We are planning to use the Amplifier TPA3139D2 , we have the requirement of 2X4W speaker so kindly let us know if we can use this amplifier and what will be the input voltage for this amplifier and confirm the…
Part Number: TPA3139D2 Tool/software: I have designed this for BD mode and its working now I want to convert the design to 1SPW mode .After configuring the speaker is not working so I need some review and confirmation on the calculation i have made
…
Part Number: TPA3139D2 Tool/software: I am looking to use TPA3139D2 in a precision motor drive application but it looks like it may not work due to the DC detect feature. From what I understand if there is a DC current on the output that lasts 800ms the…
Part Number: TPA3139D2 Tool/software: TPA3139D2RGER i am using this chip for driving a stereo speaker they are 2 watt speakers each how do i set the power limit to 2 watts how do i properly set the power limit ?
Part Number: TPA3139D2 Hi,
I am using TPA3139D2 and till now I did not used PLIMIT feature. From now I want to limit output power to 1W. What is voltage divider I have to define in purpose configuring this limit. Do you have any expression for calculation…
Part Number: TPA3139D2 Tool/software: Hi,
We are using TPA 3139D2 chip for audio class D amplifier. While testing, the chip is entering into shutdown mode ( low ), as per design we pulled it to high to AVcc (12V) through 100 K resistor. How to enter…
Part Number: TPA3139D2 Hi,
I have several question about TPA3139D2 Class D Amplifier.
1) In datasheet chapter 6.1 absolute Maximum Ratings. Minimum load Resistor is 4.8 ohm @ BTL, (10V < PVCC <14.4V) condition.
But 4 ohm speaker application…
Part Number: TPA3139D2 Hello,
I use a TPA3139D2RGER, I have high current consumption 320mA when I SD/FAULT is high (3V3) and mute is Low (0V). Can you confirm that is this current consumption is normal ? I can't find this information in the datasheet…
